The 8x57 is a good round. For anyone loading one, I suggest buying one box of Norma ammo, and loading to it's web size on firing.

You'll then see you can about duplicate the .30/06 if similar barrel length.

For a handloader, they are equal. For someone who shoots factory only, and only buys US made, it's barely better than a .30/30 - 20"carbine.
